Yintoni uhlobo lwebheri etywiniweyo, uhlobo lwetywina lokuthwala

 

I-bearing ebizwa ngokuba yi-sealed bearing yi-bearing engangeni luthuli, ukuze i-bearing ivalwe kakuhle ukuze i-bearing ihlale ithambile kwaye ikwimeko yokusebenza eqhelekileyo, inike ukusebenza okugcweleyo kwe-bearing, yandise ubomi benkonzo ye-bearing, kwaye ibe ne-seal efanelekileyo ye-rolling bearing ukuze kuthintelwe ukuvuza kwe-agent e-smoothing kunye nokungena kothuli, umphunga wamanzi okanye olunye uthuli. Oku kunceda ekukhuseleni i-bearing.

 

Uhlobo lweSitywina sokuBearing:

TUlwakhiwo lwesixhobo sokutywina lweebheringi eziqengqelekayo lwahlulwe ngokubanzi zibe ziitywini zoqhagamshelwano kunye nezitywini ezingaqhagamshelaniyo.

 

Ukutywinwa kweebheringi okungadibaniyo

 

Ukutywina okungadibaniyo kwebheri yindlela yokutywina eyila umsantsa omncinci phakathi kweshaft kunye nesigqubuthelo sokugqibela sendlu yokutywina. Olu hlobo lwesakhiwo sokutywina aludibani nomphini, ngoko ke akukho kungqubana nokuguguleka, kwaye lufanelekile ukujikeleza ngesantya esiphezulu. Ukuphucula isiphumo sokutywina, umsantsa ungazaliswa ngamafutha. Ukutywina okungadibaniyo kwebheri kuquka ikakhulu: ukutywina kwesithuba, ukutywina kwe-oyile, ukutywina kwe-labyrinth, ukutywina kwe-oyile slinger, njl.

 

1. Ukuvala izikhewu

Isitywino sesithuba senzelwe ukushiya umsantsa omncinci ojikelezayo phakathi kweshaft kunye nesigqubuthelo sebheying ngomngxuma, umsantsa weradius yi-0.1-0.3mm, okukhona umsantsa umncinci kwaye umncinci, kokukhona umphumo wokutywina ungcono.

 

2. Ukutywinwa kwe-oyile emseleni

 

Itywina yeoyile licutshungulwa ngomjelo weoyile ojikelezayo kwijenali yomngxuma wangaphakathi wesigqubuthelo sesiphelo setywina lokuthwala, kwaye umjelo wesikhokelo seoyile usasazwa ngemitha, kwaye ioyile nganye ojikelezayo inxibelelana ngomjelo wesikhokelo seoyile kwaye inxibelelana netanki yeoyile, kwaye inani lomjelo weoyile ojikelezayo kunye nomjelo wesikhokelo seoyile limiselwa bubungakanani besigqubuthelo sesiphelo setywina.

 

3. Ukutywinwa kweLabyrinth

Umgaqo osisiseko wolu tywino kukudala umjelo wokuhamba kwamanzi kwisitywino onokuxhathisa kakhulu ukuhamba kwamanzi. Ngokwesakhiwo, kwakheka umsantsa omncinci onamaqhuqhuva phakathi kwenxalenye engashukumiyo kunye nenxalenye ejikelezayo ukuze kwenziwe "i-labyrinth".

 

4. Ukutywina i-oyile slinger

 

Izitywino zoqhagamshelwano zeebheringi

Ukutywina okuqhagamshelanayo yindlela yokutywina yesiphelo okanye imilebe yomngxuma woqhagamshelwano ngerabha eyenziwe nge-vulcanized kwi-skeleton yentsimbi, kwaye ukusebenza kwayo kokutywina kungcono kunokotywina okungabonakaliyo, kodwa ukungqubana kukhulu, kwaye ukunyuka kobushushu kuphezulu. Indawo yoqhagamshelwano yomngxuma kunye nesitywina kufuneka ithanjiswe, idla ngokuthambisa nge-lubricant efanayo ne-bearing. Izitywina zokuqhagamshelana ziquka ikakhulu: ukutywina kwendandatho yefelt, ukutywina isitya sesikhumba, ukutywina kwendandatho yokutywina, ukutywina kwe-skeleton, ukutywina kwendandatho yokutywina, njl.

 

1. Ukutywinwa kwendandatho ye-Felt

Umjelo wetrapezoidal uyavulwa kwisigqubuthelo sebheyi, kwaye i-felt encinci yenxalenye yexande ibekwa kumjelo wetrapezoidal ukuze iqhagamshelane nomjelo, okanye i-gland icinezelwe nge-axial ukwenza iringi yefelt icinezelwe kwaye ivelise uxinzelelo lwe-radial ukuze ibambe umjelo, ukuze kufezekiswe injongo yokutywina.

 

2.Isitya sesikhumba sivaliwe

 

Isitya sesikhumba esivaliweyo (esenziwe ngezinto ezifana nerabha etsalwa yioyile) sifakwa kwisigqubuthelo sebheyiri size sicinezelwe ngqo kwishafti. Ukuze kuphuculwe isiphumo sokutywinwa, kucinezelwa i-ring coil spring kwiringi engaphakathi yesitya sesikhumba, ukuze i-ring engaphakathi yesitya sesikhumba ilingane kakuhle neshafti..

 

3. Indandatho yokutywina ivaliwe

Izitywino zihlala zenziwe ngesikhumba, iplastiki okanye ngerabha engangeni mafutha kwaye zingenziwa kwiiprofayili ezahlukeneyo njengoko kufuneka. Isangqa sokutywina esinobume obungu-0 sineprofayili ejikelezayo, exhomekeke kumandla ayo e-elastic ukuze icinezele kwi-shaft, enesakhiwo esilula kunye nokuhlanganiswa okulula kunye nokuqhaqha. Izitywino ezibume obungu-J kunye no-U nazo zisetyenziswa rhoqo, zombini zinesakhiwo esibume obufana nemilebe.

 

4. Ukutywinwa kwamathambo

 

Ukuze kuphuculwe amandla apheleleyo esitywino sesitya sesikhumba, i-lining yesinyithi ene-cross-section efana ne-L kunye nesimo se-annular ifakwe kwirabha engangenisi mafutha, ukuze isitywino sesitya sesikhumba singabi lula ukusiguqula, kwaye ubomi benkonzo buphuculwe Kwimeko ye-<7m/s, uninzi lweebhokisi zokuthwala iipompo ze-centrifugal ngoku zivaliwe nge-skeleton.

 

5. Ukutywina iringi yokutywina

Olu luhlobo lwesitywino esijikelezayo esine-notch, sibekwe kwi-groove yeringi yesitywino, isitywino sijikeleza kunye ne-shaft, kwaye iringi yokutywina icinezelwe eludongeni lomngxuma wangaphakathi wenxalenye emileyo ngokuthamba kwayo xa i-notch icinezelwe, kwaye inokudlala indima yokutywina, kwaye olu hlobo lokutywina luyinkimbinkimbi ngakumbi.

 

Ukukhethwa kwesakhiwo sesitywina sokuthwala

 

Xa ukhetha isakhiwo sesitywino sebheyari, izinto eziphambili ekufuneka ziqwalaselwe zezi: i-lubricant, oko kukuthi, nokuba yioyile okanye i-grease; Isantya esithe tye seendawo zokutywina; impazamo yokufakwa kwe-shaft; Ubungakanani kunye nexabiso lendawo yokufaka, njl.
